Real estate agents can help maximize the financial outcome of a property sale or purchase by making strategic improvements that enhance value. A case study describes a commercial building that received only cosmetic upgrades like painting costing $10,000, increasing its sale price from $700,000 to $850,000. Another case discusses a fixer home in Berkeley Hills that sold for $1,250,000 after $100,000 in renovations like new decks and kitchen, up from an estimated $825,000. Preparing properties by addressing issues and balancing positive and negative characteristics can help overcome buyers' cognitive biases and lead to better decisions.
